In case if you forgot or missed to upload and save some of your invoices for GSTR 1 then it is important to include those invoices in GSTR 1. But after submission of GSTR 1, it is not allowed to make changes in filed/ submitted GSTR 1 as well as there is no concept of revised GSTR 1 under GST return process.
